SHOP DRAWINGS HIGH PRESSURE STEAM PUMPED ROVANCO PIPING SYSTEM.pdf

This document is a specification and installation manual for a high-pressure steam and pumped condensate piping system. The specification section 33 63 00 includes complete shop drawings for the system's design, along with comprehensive field installation instructions for the Rovanco Insul-800 High Temperature Conduit System.

The Insul-800 system is designed for underground high-temperature applications (210°F and above) and consists of a steel, copper, or stainless steel carrier pipe with mineral wool or high-temp foam insulation, enclosed in a 10-gauge steel inner conduit casing with a polyethylene outer jacket. The system is drainable, dryable, and air-testable. Installation requirements include carrier pipe welding with hydrostatic testing at 1.5 times operating pressure (not exceeding 250 psig), cold springing procedures for expansion loops, field joint insulation using sectional or poured-in-place foam, connector band welding and air testing at 15 psig, and concrete anchor placement. The specification mandates all carrier pipes undergo hydrostatic testing and conduits undergo air testing prior to pouring thrust blocks or backfilling. Additional requirements cover test can application, inner conduit casing insulation and sealing, concrete anchor pouring, system backfilling with clean material, inner conduit casing drying procedures, manhole and building entry details, and annual maintenance including drain plug inspection, yearly air testing at 15 psig, and insulation leak detection. The standard specifications reference ANSI B31.1 standards and require certification testing by independent agencies for insulation materials.
